Nemesia plant named ‘Finemangstraw’

ABSTRACT

A new and distinct cultivar of  Nemesia  plant named ‘Finemangstraw’, characterized by its upright, outwardly spreading and uniformly mounded growth habit; freely branching and flowering plant habit; large red-colored flowers that are fragrant; relatively tolerant to high temperatures; and good garden performance.

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘FINEMANGSTRAW’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesiaplant, botanically known as Nemesia hybrida and hereinafter referred toby the name ‘Finemangstraw’.

The new Nemesia plant is a product of a planned breeding programconducted by the Inventor in De Lier, The Netherlands. The objective ofthe breeding program is to create new Nemesia plants with good vigor andattractive flower coloration.

The new Nemesia plant is a naturally-occurring branch mutation ofNemesia hybrida ‘Kirine-15’, disclosed in U.S. Plant Pat. No. 18,270.The new Nemesia plant was discovered and selected by the Inventor on asingle flowering plant of ‘Kirine-15’ within a population of plants of‘Kirine-15’ in a controlled greenhouse environment in De Lier, TheNetherlands in April, 2009.

Asexual reproduction of the new Nemesia plant by terminal cuttings in acontrolled environment in De Lier, The Netherlands since April, 2009 hasshown that the unique features of this new Nemesia plant are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Nemesia have not been observed under all possibleenvironmental conditions and cultural practices. The phenotype may varysomewhat with variations in environmental conditions such as temperatureand light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Finemangstraw’. These characteristicsin combination distinguish ‘Finemangstraw’ as a new and distinct Nemesiaplant:

-   -   1. Upright, outwardly spreading and uniformly mounded growth        habit.    -   2. Freely branching and flowering plant habit.    -   3. Large bright red-colored flowers that are fragrant.    -   4. Relatively tolerant to high temperatures.    -   5. Good garden performance.

Plants of the new Nemesia can be compared to plants of the parent,‘Kirine-15’. Plants of the new Nemesia differ primarily from ‘Kirine-15’in flower color as plants of ‘Kirine-5’ have orange-colored flowers.

Plants of the new Nemesia can also be compared to plants of the Nemesiahybrida ‘Intrairedtwo’, disclosed in U.S. Plant Pat. No. 23,061. Inside-by-side comparisons conducted in De Lier, The Netherlands, plantsof the new Nemesia differed primarily from plants of ‘Intrairedtwo’ inthe following characteristics:

-   -   1. Plants of the new Nemesia were not as trailing as plants of        ‘Intrairedtwo’.    -   2. Plants of the new Nemesia flowered earlier than plants of        ‘Intrairedtwo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Nemesia plant showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Nemesia plant.

The photograph comprises a side perspective view of a typical floweringplant of ‘Finemangstraw’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and following descriptionwere grown under environmental conditions and cultural practices whichclosely approximate commercial production conditions during the summerand autumn in 12-cm containers in a glass-covered greenhouse in De Lier,The Netherlands. During the production of the plants, day temperaturesranged from 17° C. to 30° C. and night temperatures ranged from 16° C.to 18° C. Plants were pinched about two weeks after planting and wereeight weeks old when the photograph and description were taken. In thefollowing description, color references are made to The RoyalHorticultural Society Colour Chart, Fifth Edition, except where generalterms of ordinary dictionary significance are used.
